What is Polyester Needle Felt?
Polyester needle-punched felt is made of polyester fiber, polyester fiber, viscose fiber, polypropylene fiber, etc. and is made by the needle-punching process.
Polyester needle felt properties
1. Polyester needle-punched felt is a fixed arrangement of fine short fibers with uniform pore distribution to filter air with a porosity of 70%, twice that of woven filter cloth.
2. High dust removal efficiency and low gas emission density.
3. The surface of polyester needle-punched felt is smooth after hot rolling and singeing or coating, not easy to block, not deformed, easy to clean and has a long service life.
4. Anti-static needle-punch felt - anti-corrosion and electrostatic discharge of blast furnace gas and coal mill bags in cement plant dust collection and static electricity collection functions.
The main use of polyester needle felt
Products are widely used in machinery, metallurgy, mining, forestry, textile, electromechanical, communication, materials, and transportation. Surface treatment of products in aviation, ship mooring, machinery, electronics, home appliances, electromechanical, hardware, furniture, rubber and other industries.
